Computer Assisted Field Entry (CAFE) can literally make the difference between the success and the failure of a survey, as some recent experiences have shown. There are very few complex surveys that have succeeded without CAFE, and few complex surveys that have failed with CAFE. Notice the word 'complex' in the last statement. Many successful surveys were implemented before CAFE, but they were not as complex as the surveys we are trying to implement in the HRBF and similar programs.
